Use 3.14 for the value of , and round your answers to two decimal places, where applicable. If the diameter of a circle is 15 m,
sergejj [24]

if the diameter of a circle is 15, its radius is half that or 7.5.

\bf \textit{area of a circle}\\\\ A=\pi r^2~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ r=7.5 \end{cases} A=\pi (7.5)^2\implies A=56.25\pi \implies \stackrel{\pi =3.14}{A=176.625}

The cheetah is 7/6 the Perigen falcon is 10/3
Brilliant_brown [7]
The answer is 2  \frac{1}{6}.

Explanation:

In order to subtract the fractions, we must make them like fractions. To do this, the denominators must be the same by multiplying (only). Since the first fraction is \frac{10}{3}, 3 can be multiplied by 2 to get 6, which is the other fraction, we can multiply it. Whatever you do to the denominator you must do to the numerator. Now multiply 2 by the numerator (10) to get \frac{20}{6}. Now we can subtract the fractions \frac{20}{6} and \frac{7}{6} to get 13/6. Since this fraction is not in mixed fraction form yet, we must do that first.  goes into 13 twice, so the whole number is 2 and there is still 1 left, making the fraction \frac{1}{6}. Therefore, the difference is 2 \frac{1}{6}.
